What is radioactive dating wikianswers

Though the least powerful of the three types of radiation, alpha particles are nonetheless the most densely ionizing of the three.

That means when alpha rays can cause mutations in any living tissue they come into contact with, potentially causing unusual chemical reactions in the cell and possible cancer.

They are likely to be emitted alongside alpha and beta radiation, though some isotopes emit gamma radiation exclusively.

Alpha particles are most commonly used in smoke alarms.

These alarms contain a tiny amount of decaying Americium between two sheets of metal. A small electric current is then passed through one of the sheets and into the second one.

The leak will be identified wherever the count on the Geiger-Muller tube spikes, indicating a large presence of gamma radiation coming out of the pipes.

Radiocarbon dating is used to determine the age of once-living tissue, including objects like string, rope, and boats, all of which were made from living tissue.

Even with such intense barriers, some radiation may still get through because of how small the rays are.

Though the least ionising of all the forms of radiation, that doesn't mean Gamma rays aren't dangerous.Beta radiation consists of an electron and is characterized by its high energy and speed.Beta radiation is more hazardous because, like alpha radiation, it can cause ionisation of living cells.They are therefore often used to fight cancer and to sterilise food, and kinds of medical equipment that would either melt or become compromised by bleaches and other disinfectants. In those situations, a gamma ray source is placed into the substance flowing through the pipe.Then, someone with a Geiger-Muller tube above-ground will measure the radiation given off.All living cells take up carbon-14, whether from photosynthesis or eating other living cells.
